Email form not working

I have set up my website. it all seems to work apart from the Email form. I have input my company admin email address. this is for general Email . but when I run it in the web browser and try to send am email to my company, I get a download advert from mobirise. some one said I need to register the company email address. is this correct?? If so haw do I do it??Or dose the Email form only work when the website has been published on the net. ??

Used a wrong address first and the the right one. Is the Formoid account manageable, i.e. can I LOG OUT somewhere to re-log in into the different account, that seems to be associated with the other email-address?
